Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing combined machine tools, and relates to a static and dynamic scroll plate, a multi-station turning and milling one-step finishing equipment thereof, and a using method thereof. Background Art

[0002] In the field of scroll compressor manufacturing, as the core components, the static and dynamic scroll plates' machining accuracy and efficiency directly affect the overall performance and manufacturing cost of the compressor. The traditional machining method of scroll plates often adopts a single-station and multi-process machining mode, that is, different processes such as turning, milling, and chamfering are completed by multiple devices respectively. This machining method has many drawbacks.

[0003] On the one hand, the traditional machining method is inefficient. Since it is necessary to frequently transfer and clamp the workpiece between different devices, it not only increases the manual operation time and labor intensity, but also easily causes the workpiece to be damaged or mispositioned during the transfer process, thus affecting the machining accuracy. In addition, in the single-station machining mode, the device is idle when machining one workpiece, and the device resources cannot be fully utilized, resulting in low overall machining efficiency.

[0004] On the other hand, the traditional machining method is difficult to guarantee the machining accuracy. During the multi-process machining process, each clamping may introduce new positioning errors, and the accumulation of these errors will significantly reduce the machining accuracy of the workpiece. Especially for parts like scroll plates with extremely high precision requirements, tiny errors may lead to a decline or even failure of the compressor performance. In addition, the traditional chamfering process often relies on manual operation, which is not only inefficient, but also difficult to guarantee the chamfering quality and consistency.

[0005] At the same time, during the machining process of the existing static and dynamic scroll plates, an internal expansion clamping cylinder is relied on for clamping. When the cutting amount is large, displacement is likely to occur, affecting the machining accuracy.

[0006] Therefore, we propose a static and dynamic scroll plate, a multi-station turning and milling one-step finishing equipment thereof, and a using method thereof to solve the above-mentioned problems. Summary of the Invention

The moving scroll disk bottom 3 and the moving scroll teeth 2 are manufactured by an integral molding process to ensure the integrity and strength of its structure. A positioning groove 4 is provided at the bottom of the moving scroll disk bottom 3, and this positioning groove 4 is used for positioning during the processing to ensure the accurate position of the moving scroll disk 1 during processing. In addition, a circular column 6 is also provided at the bottom of the moving scroll disk bottom 3, and this circular column 6 can be used for cooperation or positioning with other components.

[0063] The stationary scroll disk 7 is composed of a stationary scroll disk bottom 8, an outer ring 9 and stationary scroll teeth 10, and is also manufactured by an integral molding process. The stationary scroll teeth 10 are located inside the outer ring 9 to form a specific scroll shape. A plurality of mounting holes 12 are provided at the top of the stationary scroll disk bottom 8, and these mounting holes 12 are used to mount the stationary scroll disk 7 to the corresponding equipment. A convex column 11 is provided at the top end of the outer ring 9, and this convex column 11 can be used for cooperation or positioning with other components.

[0064] Fixing grooves 5 are provided on the outer walls of both the moving scroll disk bottom 3 and the stationary scroll disk bottom 8, and these fixing grooves 5 are used for clamping during the processing to ensure the stability of the scroll disk during processing.

[0065] Embodiment 2

[0066] Refer to Figures 4-10, a multi-station turning and milling one-step fine machining equipment for machining the above-mentioned dynamic and static scroll disks, including components such as a machining center 13, a fixture table 17, a first corner pressing cylinder 20, and a second corner pressing cylinder 22.

[0067] Inside the machining center 13, there is a lifting table 14. At the bottom end of the lifting table 14, there are four groups of spindles 15. At the bottom end of the spindle 15, there is a milling cutter 16, and a fine adjustment setscrew is arranged on the shank of the milling cutter 16. Inside the machining center 13, there is also a tool magazine that cooperates with the spindle 15 for storing and replacing different milling cutters 16 to meet the requirements of different machining processes.

[0068] The fixture table 17 is arranged on the workpiece table inside the machining center 13 through bolts. At its top, there are two groups of rotary cylinders 18 connected by bolts, and the number of each group of rotary cylinders 18 is four. The output end of the rotary cylinder 18 is connected to a clamping cylinder 19 through bolts, and a shock pad can be installed between them. The clamping cylinder 19 is used to clamp the dynamic scroll disk 1, enabling multiple dynamic scroll disks 1 to be clamped at one time, which can improve the machining efficiency. The clamping cylinder 19 adopts a pneumatic integrated internal support clamp seat from Desheng Precision Technology and is externally sleeved with an annular protective sleeve.

[0069] There is a detection head 25 on the clamping cylinder 19. The detection head 25 includes a first connecting pipe 26 fixedly arranged through the top of the annular protective sleeve of the clamping cylinder 19. At the top of the first connecting pipe 26, there is a cylinder body 27 welded. A sliding rod 29 is slidably arranged through the top of the cylinder body 27. At the top end of the sliding rod 29, there is a sealing plate 31 for sealing the top end of the cylinder body 27. The two ends of the sliding rod 29 are sleeved with a first spring 30. The two ends of the first spring 30 respectively abut against the bottom wall of the cylinder body 27 and the bottom of the sealing plate 31 through connecting seats. The sealing plate 31 is provided with a sealing ring to increase the sealing performance. An air inlet hole 28 communicating with the first connecting pipe 26 is opened at the bottom of the cylinder body 27. By detecting the air pressure inside the cylinder body 27, it can be judged whether the dynamic scroll disk 1 is placed in place. The principle is that during the placement of the dynamic scroll disk 1, it will squeeze the sealing plate 31 to move downward, so that it moves into the cylinder body 27 and can seal the top end of the cylinder body 27. When inflating into the cylinder body 27, since the cylinder body 27 is in a sealed state, the internal air pressure will increase. When it is not placed in place, the sealing plate 31 will not seal the cylinder body 27, and the gas inside the cylinder body 27 will leak. In addition, a plurality of rubber pads 24 are adhesively bonded to the top end of the clamping cylinder 19 to increase the friction during clamping and ensure the stability of the dynamic scroll disk 1.

[0070] A plurality of first corner downward pressure cylinders 20 are arranged in a ring on the top of the fixture table 17 with the rotating cylinder 18 as the center, and the number corresponds to the fixing grooves 5 on the outer walls of the movable scroll bottom 3 and the fixed scroll bottom 8. The output end of the first corner downward pressure cylinder 20 is connected to a clamping block 21 used in conjunction with the fixing groove 5 by bolts, and the working surface thereof is processed with serrations for fixing the movable scroll 1 during the processing, such as Figure 5 As shown, the clamping block 21 is in an unclamped state.

[0071] The two sets of second corner pressing cylinders 22 are fixed to the top of the fixture table 17 by bolts. The number of each set of second corner pressing cylinders 22 is two and they are located between two adjacent clamping cylinders 19. The output ends of the second corner pressing cylinders 22 are connected to the swing rods 23 by bolts. The bottoms of both ends of the swing rods 23 are fixed with pressure plates 34. Figure 5 As shown, the pressure plate 34 is in a reset state, and after rotating and pressing down, it is located at the top of the two movable scroll plates 1. The pressure plate 34 is provided with a first chamfering component for chamfering the movable scroll bottom 3 and a second chamfering component for chamfering the top of the movable scroll tooth 2. In addition, the pressure plate 34 is also provided with a cleaning component for cleaning impurities on the top of the clamping cylinder 19.

[0072] The first chamfering assembly includes a rotating ring 37 that is rotatably sleeved on the outer wall of the pressure plate 34. A plurality of first scrapers 36 (HRC60-62) are welded to the outer wall of the rotating ring 37. The first scraper 36 is in an eight-shaped shape and can chamfer and remove burrs at the top and bottom corners of the movable scroll bottom 3. A screw 38 is provided through the thread on the outer wall of the rotating ring 37 to fix the position of the rotating ring 37. During the chamfering process, the clamping cylinder 19 and the movable scroll 1 are driven to rotate by the rotating cylinder 18, and the top and bottom corners of the movable scroll bottom 3 are chamfered by the first scraper 36, so that it does not need to be manually removed by using an additional scraper, and the movable scroll bottom 3 is larger than the diameter of the top of the clamping cylinder 19 to avoid the first scraper 36 from interfering with the clamping cylinder 19.

[0073] The second chamfering assembly includes a sliding seat 42 movably arranged at the bottom of the pressure plate 34, and a second scraper 43 is arranged in the sliding seat 42. The two pressure plates 34 are arranged in a V shape to better adapt to the shape of the moving scroll tooth 2. Two fixing seats 44 are welded to the bottom of the pressure plate 34, and a guide rod 39 is welded between the two fixing seats 44. The sliding seat 42 is slidably sleeved on the guide rod 39 by a chute-slider, and a second spring 40 and a third spring 41 are sleeved on the outer wall of the guide rod 39. The second spring 40 and the third spring 41 are located on both sides of the sliding seat 42, and their two ends respectively abut against the mutually close sides of the sliding seat 42 and the fixing seat 44, so as to limit the sliding seat 42 by using the second spring 40 and the third spring 41. During the chamfering process, the pressure plate 34 is driven to move downward by the second rotation angle pressing cylinder 22, so that the second scraper 43 contacts the middle part of the moving scroll tooth 2. Then, the clamping cylinder 19 and the moving scroll disk 1 are driven to rotate, and the moving scroll tooth 2 is used to drive the second scraper 43 to reciprocate, so as to chamfer the top end of the moving scroll tooth 2 in sequence. And when pressing down the moving scroll disk 1, the second scraper 43 can correspond to the ramp of the moving scroll tooth 2 to avoid the second scraper 43 from contacting the moving scroll tooth 2.

[0074] The cleaning assembly includes a second connecting pipe 32 corresponding to the second rotation angle pressing cylinder 22. The second connecting pipe 32 penetrates and is fixedly arranged at the top end of the fixture table 17. A third connecting pipe 35 is fixedly arranged on one side of the swing rod 23. The two ends of the third connecting pipe 35 are respectively communicated with the two pressure plates 34. The pressure plate 34 is hollow, and a plurality of air outlet holes 45 are opened at its bottom. The top end of the second connecting pipe 32 is communicated with the third connecting pipe 35 through a connecting hose 33. During the cleaning process, by opening the external air source, the gas can enter the pressure plate 34 through the second connecting pipe 32, the connecting hose 33, and the third connecting pipe 35, and finally spray out from the air inlet and outlet holes 28 to clean the impurities on the surface of the clamping cylinder 19, which can improve the clamping efficiency and accuracy.

[0075] During processing, first, the second rotation angle pressing cylinder 22 is started to rotate by the controller. During the rotation of the second rotation angle pressing cylinder 22, the swing rod 23 can be driven to swing, so that the two pressure plates 34 move to the top of the clamping cylinder 19, and the external air source is opened. The gas can enter the pressure plate 34 through the second connecting pipe 32, the connecting hose 33, and the third connecting pipe 35, and finally spray out from the air outlet holes 45, so as to clean the impurities on the surface of the clamping cylinder 19. Then, the second rotation angle pressing cylinder 22 is started to rotate back to its original position;

[0076] Place the moving scroll disk 1 on the corresponding clamping cylinder 19, and make the detection head 25 stuck in the corresponding positioning groove 4. Start the second angular pressing cylinder 22 to rotate, drive the pressing plate 34 to move above the moving scroll disk 1, and press down. The moving scroll disk 1 can be pressed onto the clamping cylinder 19. During the pressing process, the moving scroll disk 1 can press the sealing plate 31 to move downward, so that the sealing plate 31 seals the top of the cylinder body 27. Start the clamping cylinder 19 to expand outward to clamp the moving scroll disk 1, and start the external air source to inflate the cylinder body 27 and detect the air pressure. When the air pressure is less than the set value, the placement is unqualified and needs to be re-placed. When the air pressure is equal to the set value, the placement is qualified. Until all the moving scroll disks 1 are placed qualified, start the second angular pressing cylinder 22 to reset;

[0077] Start the machining center 13 to first machine the outer circle of the bottom of the moving scroll 3, and then replace the milling cutter 16 to mill the fixing groove 5 on the outer wall of the bottom of the moving scroll 3. After the milling is completed, start the first angular pressing cylinder 20 to drive the clamping block 21 to move upward, and then control the clamping block 21 to rotate so that the clamping block 21 moves into the fixing groove 5. Then control the first angular pressing cylinder 20 to retract, drive the clamping block 21 to move downward, and cooperate with the fixing groove 5 again to fix the moving scroll disk 1 on the clamping cylinder 19;

[0078] Then start the machining center 13 to replace the milling cutter 16 and machine the moving scroll teeth 2 until the machining is completed;

[0079] Start the second angular pressing cylinder 22 to rotate, drive the swing rod 23 to approach the moving scroll disk 1. At the same time, start the rotary cylinder 18 to drive the clamping cylinder 19 to rotate, which can drive the moving scroll disk 1 to rotate. During the rotation process, the first scraper 36 can be used to chamfer the top and bottom corners of the bottom of the moving scroll 3;

[0080] Then drive the second angular pressing cylinder 22 to extend and rotate until the pressing plate 34 moves to the top of the moving scroll disk 1. Then control the second angular pressing cylinder 22 to retract. During the retraction process, drive the pressing plate 34 to move downward, so that the second scraper 43 can contact the middle teeth of the moving scroll teeth 2. Then drive the clamping cylinder 19 to rotate. During the rotation of the moving scroll disk 1, the moving scroll teeth 2 can drive the second scraper 43 to reciprocate, and chamfer the top of the moving scroll teeth 2 in turn.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
